In Piaget's stages of cognitive development, which phase typically emerges in adolescence and involves thinking about abstract ideas and complex social situations?

Explanation

The formal operational stage is the phase in Piaget's theory that begins in adolescence, marked by the capacity to think abstractly, logically, and about hypothetical scenarios, including understanding complex social dynamics. The concrete operational stage involves logical thinking but is limited to tangible, concrete concepts, while the sensorimotor stage is characteristic of infancy, focusing on sensory and motor interactions. Postformal thought is a concept beyond Piaget's original stages.
